EJECTOR-CONDENSER.

SPECIFICATION forming part of Letters Patent No. 393,488, dated November 27, 1888.

Application filed November 5,1887. Serial No. 254,403.

To all whom it may concern:

Be it known that I, LoUIs Sci-iU'rrE,of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain Improvementsin Ejector-Gondensers,ol` which the following is a specification.

My present invention has reference to that class of ejector-condensers in which the exhaust-steam or other steam to be condensed is admitted through a series of openings inv a combining-tube to a central water jet or column, and relates more particularly to improvements on condenscrs such as represented in Letters Patent of the United States No. 830,157, dated November l0, 1885, and No. 344, 502, dated June 20, 1886,Wherein a movable arm or spindle is used Within the nozzles to change the areas of the water-nozzle and discharge-nozzle.

In Patent No. 330,157 the capacity of the apparatus is varied by reducing or increasing the waterpassages,while the openings for the admission of the exhaust-steam are unchangeable. Now, as the operation of the condenser depends on the action of the exhauststeam on the water-column to impart thereto the necessary speed, it will be apparent that the exhaust-steam must have a certain speed and corresponding pressure to maintain the movement of the Water. If, now, the total area ot steamadmission openings in the combiningtube be larger than is required to compel a certain speed for a certain Volume, the action of the condenser will become uncertain, and. a reduction in the size of the waterjet alone, as provided for in said patent, may be insuflicient to give a satisfactory regulation for the required reduction in the capacity of the condenser to meet a steam-supply. To meet this condition, I now provide a means for ef fecting a corresponding reduction or increase in the steaminlet passages or holes of the com* biningtube. This may be eli'ected either by reducing the number of steam-inlets or by reducing their size, the effect being in either case to lessen the area of the steam-admission passages.

As my apparatus may be in all other respects identical with that represented in Letters Patent No. 830,157, I have represented in the accompanying drawings only those por- (No model.)

tions which are immediately connected with my present improvement.

Referring to the drawings, Figure 1 is an axial section through a condenser having my improvement incorporated therein, the construction being such as to effect a change in the area of all the steam-admission openings. Fig. 2 is a side view, partially in section, of one of the sections or nozzles of which the combining-tube is composed. Fig. 3 is a cross section on the line .fr m of Fig. l. Fig. 4 is a section through the combiningtube and adjacent parts of the apparatus in a modified form, with means i'or closing certain of the steamadmission openings. Fig. 5 is a cross-section on the line y y of Fig. 4.

In its principal features the apparatus herein represented is substantially identical with that shown in Letters Patent No. 344,502, the corresponding parts of the two apparatus being indicated by the same letters.

Referring to the drawings, A represents a central nozzle for the admission of live steam to initiate the operation of the apparatus; B, the water-admission nozzle, through which the steam-jet is directed, D, the combining-tube, through which the water'j et is directed; E, the chamber surrounding the combining-tube and into which the exhaust-steam is iirst delivered; G, the central longitudinal adjustable spindle or ram by which the inlet of the waterfpassage is adjusted; a, the overiiow-valve for starting purposes; d, a screw entering the end of the ram to adjust the same, and e an external hand-Wheel by which the adj listing-screw is turned.

The foregoing parts correspond with those in the patent before alluded to.

The combining-tube is provided, as in the original apparatus, with a number of steamadmission openings, z, through which the steam passes from the chamber E to the ceutral water-jet, impiuging on the latter in a forward direction in order to impart the required motion thereto.

Referring to Figs. 1, 2, and 3, it will be seen that the combining-tube, instead of being constructed, as in the original patent, in a rigid manner, is composed of a series of small nozzles, k, arranged to discharge one into another, with annular spaces between them for ICO V- the series ofnozzles being thus connected so that they constitutejointly a rigid combiningtube. .lhe width or area ofthe annular spaces or steam-inlets between the adjacent nozzles may be increased or diminished by screwing one nozzle into or out of the other. In order to effect this adjustment, I mount in suitable bearings within the body, adjacent to the coinbining-tube, a long pinion, N. This pinion engages the teeth ol' the alternate nozzles for the purpose of rotating the same, and passes loosely through the projections k" of the intermediate nozzles to prevent their rotation. When, therefore, the pinion is turned in one direction, it will have the effect of screwing the nozzles together and diminishing the width of the annular spaces between them, while its rotation in the opposite direction will have the effect of unserewing the nozzles and increasing the width of the intermediate spaces, so that the exhaust-steam will be admitted to the water-jet in increased or diminished volume, as circumstances may require.

The upper end of the pinion is provided with a bevel-pinion, l, engaging a corresponding pinion on the inner end of a spindle, m, which is extended through a stuffing-box to the exterior and provided with an operating wheel or handle, a. It is to be understood, however, that in place of these devices any other suitable means for operating the pinion N or for changing the distance between the nozzles may be substituted for those herein shown, the es sence of the invention in this form of embodiment resting in the adjustment of the nozzles to and from each other to vary the size ofthe steam-entrances.

The devices for adjusting the combining tube may be operated independently of those for adjusting the ram or spindle (l, and in most cases such arrangement will be satisfactory. Vhen, however, the volumes ol' steam and water bear fixed relations to each other, it is sometimes advisable to connect the ramadjusting and the tube-adjusting devices so that they will be operated in unison. In Fig. l I have represented a suitable connection for this purpose.

The spindle m, through which the combining-tube is adjusted, is provided with a pinion, o, engaging a pinion, p, on a shaft, q, which is in turn provided with a gear-wheel, r, engaging a pinion, s, fixed on the screw by which the ram is adj usted'.

In Fig. 4t the combiningftube is a rigid un- Each ot these nozzles is formed with changeable one, such as shown in Iatent No. 344,502. In applying my improvement to a tube of this form I provide a sleeve, O, which encirclesY the water# nozzle, and which 1s adapted to be moved downward so as to cover any desired number of the openings through the upper or receiving end'of the combiningtube. The location of this sleeve at the upper instead of the lower end of the combining-tube is advantageous, for the reason that when located at the lower end the discharge tube or throat practically commences at the upper edge of the movable sleeve, and a portion of the pressurcwater leaks past the sleeve lnto the condenser-body instead of continuing lts downward course, while, on the other hand, with the sleeve located at the top, as herein shown, the discharge tube or throat begins at a lixed unchangeable point, while the sleeve simply covers the upper steam-inlets, where a leakage is less likely to occur and where a moderate leakage will not impair the working of the apparatus, as it would if occurring at the lower end, so as to render them for the time,

being inoperative. This sleeve may be adjusted by any suitable mechanism. In the drawings, I have represented the tube as provided in one side with a horizontal slot to receive a crank-pin, t, or a disk, u, carried by a spindle, c, extending to the outside of the body, where it is provided with a hand-wheel, fw, or an equivalent operating device.

I do not claim, broadly, herein any and all means of diminishing the aggregate area of the steam-inlets, a sleeve for this purpose at the lower end of the combining-tube being old in condenscrs which are without means of regulating the size of the water throat or passage. I believe myself to be, however, the first to use a sleeve for limiting the area of the steam-inlets at the lower or delivery end of the combining-tube, and I also believe myself to be the rst to combine in any manner or form with a condenser of the type herein shown means for reducing the aggregate area of the steam-inlets through the combining-tube and means for regulating the area. of the water throat or passage within the combining-tube, and my invention is to be considered as embracing these combinations in any form the mechanical equivalent of those herein shown.

What I claim isl. In an ejector-condenser having the noz zle combiningtube and discharge -tube, as usual, the sliding sleeve O, arranged to close the steam-inlets at the upper or receiving end of the combiningtube as distinguished from a sleeve at the delivery end of said tube, whereby the aggregate area of the steamadmission openings maybe varied to maintain the required velocity of the inflowing steam without causing the leakage of water from the combining-tube int-o the condenser-body.

variable steam-inlets, the water-tube with the variable throat, and an adjusting mechanism 15 common to the two, whereby the admission of steam and water is controlled simultaneously and in proper relations.

In testimony whereof I hereunto set my hand this 12th day of October, 1887,111 the presence 2o of two attesting witnesses.
